3-34. General.
a.
Assembly of the metering and
distributing fuel inject ion pump should be performed
in figure number sequence and in accordance with
the instruct ions provided with each illustration.
b.
The fuel injection pump is a precision accessory
whose proper operation depends on cleanliness of all
parts. Precision lapped surfaces of rotating parts
must be free of dust and dirt at all times. During
assembly, keep working area, parts, hands, and
clothing clean.
c.
Immediately before assembly, coat all
bearings, shafts,
and contact surfaces with ap-
propriate engine oil. Always use new gaskets and
packings. Apply grease, Federal Specification W-P-
236, on tight fitting preformed packings to aid in
their installation.

a. General.
A number of repair
kits are supplied to repair the fuel injection pump.
